Hey Buddy...
Answer:
One of the things that has formed part of my syllabus with medical students is asking them about the cause of malaria. Before they have studied parasitology, this question elicits interesting, but reasonable, answers: bushy environments, not sleeping under a treated bednet, the rains, mosquitoes and mosquito bites.
In their final year of study, the students are sophisticated medical students. Their answers change. By now they are sure that the parasite Plasmodium species is what triggers the disease.
This answer is correct. Plasmodium species are indeed central to malaria. But what the students have forgotten is that mosquito breeding sites, poverty, and wet and warm environments also contribute to the spread of the disease.
Plasmodia constitute one of many factors that must be present for malaria to occur. To get malaria the parasite needs to be present. But other factors also have an impact on whether or not a person becomes ill.
Many people have the malaria parasite in their bloodstream but do not become ill. For example, if someone contracts malaria as a child they are likely to have developed immunity by adulthood.
But the factors that “tip” people to develop malaria from the parasite include:
a weak immune system: the parasite becomes more aggressive in the body and malaria develops;
age: younger children are likely not to have built up immunity to the disease; and
pregnancy: mothers-to-be have compromised immune systems.
The point of my lesson is that there are different causes of diseases. This is true of all diseases, not just malaria. This has led to a number of models being developed that set out to explain causation and the linkages between different variables.
Understanding what causes diseases is a life-and-death matter. The different models used by medical practitioners are a source of great contention and have generated a great deal of heated debate. If misinterpreted, or too narrowly understood, they can lead to bad decisions being made about how diseases are treated.
Hope this helps u dude

Answer:
Factors that cause disease :
Disease-causing factors may broadly be classified into 2 groups :
- Intrinsic Factors : When the disease-causing factors exit within the body itself and have not reached the body from any external source,they are known to be Intrinsic Factors.
- Extrinsic factors : When the disease-causing factors exist outside the body,they are said to be Extrinsic Factors.
